错误中被引用的行（RayIntersect.LeafIntersect的第71行是以下位置：

val io = IO(new Bundle {
如果有帮助，这里是io声明的其余部分：

val io = IO(new Bundle {
    val rayNodeStackIn = Flipped(DecoupledIO(new RayBVHNodeStackIdx(id_width, index_width)))
    val shadow         = Input(Bool())
    val rayNodeOut     = DecoupledIO(new RayBVHNode(id_width, index_width))
    val dataOut        = DecoupledIO(new Bundle {
        val foundInt = Bool()
        val f        = UInt(index_width.W)
        val its      = new Intersection()         
    })

    //Memory system interface
    val addrOut   = DecoupledIO(new Bundle {
       val id    = UInt(id_width.W)
       val trIdx = UInt(prim_id_width.W) 
    }
    val dataIn    = Flipped(DecoupledIO(new Bundle {
        val id    = UInt(id_width.W)
        val data  = UInt((new Triangle()).getWidth)
    }))
})
这是使用的捆绑软件的代码：

class Triangle() extends Bundle {
    val p0        = Vec(3, UInt(32.W))
    val p1        = Vec(3, UInt(32.W))
    val p2        = Vec(3, UInt(32.W))
    val idx       = UInt(32.W)
    val meshAddr = UInt(32.W)
}

class BVHNode() extends Bundle {
    val data = UInt(64.W)

    val bbox = new Bundle {
        val min = Vec(3, UInt(32.W))
        val max = Vec(3, UInt(32.W))
    }

    def rightChild: UInt = (data << 32) 
    def leafStart : UInt = (data << 32)
    def leafSize  : UInt = (data << 1) & 0xFFFFFFFE.U
    def start     : UInt = leafStart
    def end       : UInt = leafStart + leafSize

    def isLeaf    : Bool = data(0)

    override def cloneType = (new BVHNode()).asInstanceOf[this.type]
}

class Ray(sid_width : Int) extends Bundle {
    val origin  = Vec(3, UInt(32.W))
    val dir     = Vec(3, UInt(32.W))
    val dRcp    = Vec(3, UInt(32.W)) //Componentwise reciprocals of the ray direction
    val minT    = UInt(32.W)
    val maxT    = UInt(32.W)
    val id      = UInt(32.W)

    override def cloneType = (new Ray(sid_width)).asInstanceOf[this.type]
}

class RayBVHNodeStackIdx(id_width: Int, index_width: Int) extends Bundle {
    val ray      = new Ray(id_width)
    val node     = new BVHNode()
    val nodeIdx  = UInt(index_width.W)
    val stackIdx = UInt(index_width.W)

    override def cloneType = (new RayBVHNodeStackIdx(id_width, index_width)).asInstanceOf[this.type]
}

class RayBVHNode(id_width: Int, index_width : Int) extends Bundle {
    val ray     = new Ray(id_width)
    val node    = new BVHNode()
    val nodeIdx = UInt(index_width.W)

    override def cloneType = (new RayBVHNode(id_width, index_width)).asInstanceOf[this.type]
}

class Intersection() extends Bundle {
    val t = UInt(32.W)          //Unoccluded distance along the ray
    val u = UInt(32.W)          //UV coordinate, if any
    val v = UInt(32.W)          //Other UV coordinate
    val mesh    = UInt(32.W)            //pointer to the intersected mesh
}
据我所读，通常在尝试使用裸凿类型作为硬件时会发生此错误，但是我真的不明白为什么错误来自io声明...

有没有其他人在实现过程中遇到此问题，如果是，您是否有机会知道如何解决此问题？

[当声明新模块的io时，出现以下错误：[错误]（run-main-e）chisel3.core.Binding $ RebindingException：尝试将绑定重新分配给chisel3.core.UInt@29a [错误] chisel3。 ..

我只需稍作修改就可以运行此代码。我在.W中添加了val data = UInt((new Triangle()).getWidth.W)：
